Python: Concatenate element-wise three given lists
Python List: Exercise - 171 with Solution
Write a Python program to concatenate element-wise three given lists.
Sample Solution:
Python Code:
def concatenate_lists(l1,l2,l3):
return [i + j + k for i, j, k in zip(l1, l2, l3)]
l1 = ['0','1','2','3','4']
l2 = ['red','green','black','blue','white']
l3 = ['100','200','300','400','500']
print("Original lists:")
print(l1)
print(l2)
print(l3)
print("\nConcatenate element-wise three said lists:")
print(concatenate_lists(l1,l2,l3))
Sample Output:
Original lists: ['0', '1', '2', '3', '4'] ['red', 'green', 'black', 'blue', 'white'] ['100', '200', '300', '400', '500'] Concatenate element-wise three said lists: ['0red100', '1green200', '2black300', '3blue400', '4white500']

Python: Tips of the Day
Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:
Example:
def tips_check_prop(fn, prop): return lambda obj: fn(obj[prop]) check_age = tips_check_prop(lambda x: x >= 25, 'age') user = {'name': 'Owen', 'age': 25} print(check_age(user))
